Pictures of Nasal Polyps
This page was last updated on: November 5, 2019

Nasal Polyps are most often seen in patients with allergic rhinitis.  A nasal polyp forms gradually from localized swelling of the sinus mucosa or from the nasal mucosa..  At first, the polyp is small.  With each recurrence of submucosal edema, it becomes larger, until it appears as a smooth, pale tumor.  In most instances, polyps are multiple.  They can be moved back and forth and can cause obstructive symptoms when they protrude into the airway.  They may be large or numerous enough to occlude the nose completely.  In some instances, a single polyp arises from the maxillary antrum ostium and grows posteriorly into the choana and even down to the oropharynx.  This is called an antro-choanal polyp.

Many nasal polyps actually arise from the paranasal sinuses.  They are surgically removed through the nasal cavity under direct video monitoring with endoscopic fiberoptic telescopes attached to videocameras.  These procedures are collectively called endoscopic sinus surgery (ESS)

In severe cases, open procedures (Caldwell-Luc and external ethmoidectomy) may be used in conjunction with endoscopic procedures.

As in the picture above, if untreated, nasal polyps may cause gradual spreading of the nasal bones and widening of the nasal bridge.

In some instances, because of obstuction, a bacterial infection sets in and green nasal drainage may be seen trickling around the polyps.
